Lacus Solitudinus (latin for "Lake of Solitude") is a small lunar mare on the far side of the Moon. The selenograhic coordinates of the lake are 27.8° S, 104.3° E, and it lies within a diameter of 139 km. It forms an arcing feature with the side oriented to the northwest. The eastern edge is relatively continuous, while the west is more irregular and disrupted by small craters.

To the northwest of the northern end is the small crater Bowditch, a lava-flooded feature although it does not appear directly connected to the Lacus Solitudinus. At the western end of the mare, the eroded crater Titius lies to the northwest. To the south of this feature is Parkhurst Y, with Parkhurst itself lying some distance to the southeast.
